Yeah I agree that a lot of them are super lazy and will just disappear all semester which is absolute bullshit. However here is some context:

I teach at a college and they gave us the option to go back... However it involved:

-splitting your sections into smaller sections for "social distancing" so they'd only be in class once a week, or in some cases once every two weeks

-while teaching, also running a zoom meeting for those not in attendance. I don't know if you've ever used zoom but it's not really a set-it-and-forget-it type of thing

-of course masks, all day long

-sanitizer everything before and after use. I teach in four different classrooms so that would be fun

So I chose to go online because I thought it would be better for my students... No remember which day they are in person and which day they are zooming, no wearing face burkas... I'll still be up on campus, but livestreaming each class from my office, as close to normal as possible
